Replaced the fuel pump and filter today and it still will not start?

If you have power to the ground wire the ground is bad FYI. Here are the fuel pump wiring diagrams but I would double check the ground at the location G110. The fuel pump wiring is part of the engine wiring, so I gave you the fuel pump and the remainder of the diagrams. I would check the PCM2 fuse in the under-hood fuse panel.

Has 12 volts which completes the circuit. It has no fuel pressure could be bad ground? Or the PCM?

This Yukon Denali only has 1 fuel tank .

So, my husband found that the pump was wired different than the old one. He had to rewire it and it worked.

Glad you could get it fixed, thanks for letting us know. Please use 2CarPros anytime we are here to help.
